Alan,
My guess (and some based from my own experience), is that it supports the way a lot of non-technical clinicians like to organize the process: 1) what I want, 2) what I must avoid.
I beleive you are right that exlcusion is simply an explicit set of OR-ed negations. An interesting thing to find out would be whether there are any exclusions forms that are AND-ed negations-- in which a simple list of exclusion criteria would be insufficient.

Subject: [BIONT-DSE] Inclusion versus exclusion criteria
Something that I remain confused about is why there are two
categories of criteria, when, on the face of it, the negation of an
exclusion criterion is an inclusion criterion.
So I'm wondering, is there something between the lines? Is there
something other than the negation? Perhaps kind of criteria, or
lesser necessity, or derivation from different sources? Open versus
closed world? Otherwise, from a technical point of view can we just
consider these the the same sort of thing, with a flag indicating how
they should be shown in a hypothetical user interface?
